In order to check your Payment status you should perform the following:
1. Go to Invoice tab and click on "Toggle Filtering" button to display text box to search your invoice. Enter the Invoice number in the search box below column name "Number". It will display the invoice record if it exists in system.
2. Look for value under column Status. If it displays "PAID", then your invoice has been paid in full by your customer or is under processing stage to be remitted to your account. If Status column shows value other than PAID, then your invoice is not yet paid.
